This means they live on land and in the water. However, they can't breathe underwater. Just like me and you, they breathe oxygen and hold their breath underwater. They like to live in very warm places. You can find banded sea snakes in coral reefs throughout the South Pacific.
These snakes spend more time on land than in water. During the day, they rest on land to digest food and sleep and at night, they slither into the ocean to hunt for eels. They use their paddle-like tails to swim in the ocean and their thin body to fit into tight spots in coral to hunt for eels.
These snakes need coral reefs to find food and survive. If the world keeps getting warmer, then coral reefs won't survive and these snakes could lose their homes and food. Make sure you also keep the ocean and beach clean. Whenever you can pick up trash, a cleaner Earth is a happy Earth. These snakes will also appreciate you by wearing sunscreen lotion that is CORAL REEF SAFE!
